Not to be confused with the Green Civil War Big Muff (confusing I know), the Soviet Green Russian Big Muff only added to the military mystique associated with the Russian Produced Muff’s. Also known as the “Tall Font Muff” or the “Bubble Font Muff”, there were tonal differences between the 2. Sourcing consistent parts, even just the paint, would prove to be difficult for the Sovtek plant during the 90’s. The “Tall Font Green Russian Muff” tends to sound identical to the Civil War Big Muff, but the “Bubble Font Green Russian Muff” tends to be a bit “hairier” in tone than its predecessors. The “Bubble Font Green Russian Muff” sound happens to be a favorite of the Black Keys’ Dan Auerbach.
